Connector Terminals
Section 5-2
Input Specifications
Simultaneous Input Points and Installation Spacing
For Connector Terminals with transistor inputs, the ambient operating temper-
ature places a limit on the maximum number of points that can be turned ON
simultaneously. In addition, when installing Connector Terminals, care must
be taken to provide adequate space between them to prevent overheating.
As shown in the graphs below, the spacing of Connector Terminals varies
according to the Connector Terminal type, the ambient operating temperature,
and the number of simultaneous input points. Make the distance between
Connector Terminals greater than that shown in the graphs.
For example, if SRT2-VID16ML Connector Terminals are to be mounted verti-
cally where the ambient operating temperature will be 55
°
C and the maximum
number of simultaneous input points will be 8, the spacing of Connector Ter-
minals should be at least 10 mm.
